Most animal, insect, and plant species reproduce in pairs, or twos. In sexual reproduction, two individuals of the same species each contribute a half-set of their genes. Thus, in their whole set of genes, offspring inherit, or receive from their parents, a mixture of traits. Write down some traits that parents pass on to their offspring. In what ways do these traits help a species survive? Use the box below for your ideas.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
